What is the best lens for Nikon D5000 to shoot a wedding?
Well, I'm a photographer back in the city. I'm still studying. But I have my first job to shoot a wedding. so I'm not sure that the lens is best for shooting, please help. I desperately need help here.
Assuming you have a D5000 because you can not pay a D3s an f/2.8 14-24mm 24-70mm and 70-200mm (which is where I was) I recommend getting a 35 mm f1.8 and keep your kit lens 55 – 200mm. If you really need a better TV uses a 80-200mm f2.8 can do wonders …
